Malposition of a Port Catheter in the Azygos Vein: Endovascular Repositioning Using a Long Loop Snare Technique

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Port catheters provide a reliable, long‐term venous access option in children for repeated administration of medications or parenteral nutrition. A cardiac catheterization procedure was performed in a 7‐year‐old girl in whom lateral chest radiography revealed posterior deviation suggestive of azygos vein malposition.

An unusual cause of atrial fibrillation in a young active duty soldier

Radiology Case Reports, 2017
Coronary artery fistula (CAF) is an abnormality in which the coronary artery has an anomalous connection with a venous structure such as the coronary sinus or atrium. CAF is usually congenital, but may be acquired.

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

CASE REPORT
Additional openings of the coronary sinus and associated anomalies

Archives of Medical Science, 2006
The coronary sinus normally opens into the right atrium through a single orifice. Past research studies have described various anomalies of the coronary sinus but there are fewer reports on multiple orifices of the coronary sinus.

Late Diagnosis of Anomalous Aortic Origin of a Coronary Artery from the Inappropriate Sinus of Valsalva during Investigation of Chest Pain

Case Reports in Cardiology, 2018
In this work are reported two cases of anomalous aortic origin of a coronary artery (AAOCA), with the left main coronary artery (LMCA) arising at the right sinus of Valsalva in a 77-year-old woman and in a 79-year-old man submitted to angiography after ...

Feasibility and Safety of Distal Transradial Access in Patients With Out‐of‐Hospital Cardiac Arrest Undergoing Emergency PCI: A Single‐Center Retrospective Study

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Distal transradial access (dTRA) has gained attention for its lower risk of vascular complications compared to conventional transradial access (TRA). However, its feasibility and safety in patients with out‐of‐hospital cardiac arrest (OHCA) undergoing emergency percutaneous coronary intervention (PCI) remain uncertain.

Effect of Bileaflet Valve Orientation on the 3D Flow Dynamics in the Sinus of Valsalva

Journal of Biomechanical Science and Engineering, 2011
Three-dimensional (3D) evolutional behavior of flow dynamics in the aortic sinus of Valsalva was studied in vitro for finding the effects of bileaflet valve orientations in an effort to investigate possible linkages between the sinus flow and coronary ...

Radial Versus Femoral Access for Diagnostic Coronary Angiography: Insights From a Tertiary Academic Center in Johannesburg

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The radial artery is the preferred access for performing diagnostic coronary angiograms (DCA). However, data on the safety and efficacy of radial compared to femoral access in low‐ and middle‐income countries is limited. Aims This study aims to evaluate the safety and efficacy of radial versus femoral access in patients referred for

Multiple Coronary Arteriovenous Fistulas to the Coronary Sinus With an Unruptured Coronary Sinus Aneurysm and Restrictive Coronary Sinus Opening to the Right Atrium [PDF]

Circulation, 2009
A 37-year-old woman was transferred to our department for surgery. She had experienced intermittent chest discomfort or pain and palpitation during the last 4 years. Chest radiographs showed cardiomegaly (cardiothoracic ratio 0.63). A preoperative ECG showed normal sinus rhythm (Figure 1). Echocardiography showed marked dilatation of the coronary sinus
